Abstract

Blue (487.6nm), green (544.1nm), yellow (582.1nm), and red (623.6nm) upconversion (UC) luminescences are achieved in a Tb3+-doped lithium niobate crystal when an 800nm femtosecond laser is loosely focused onto the sample at room temperature. The relationship between UC luminescence intensity and the pump energy indicates that a two-photon excitation process is dominant in this UC luminescence phenomenon. The Tb3+ sensitive temperature dependence of the luminescence intensity is demonstrated via an obvious reduction of luminescence intensity with durative laser irradiation.
